Straddle-Type Vehicle Controller for Jump Posture Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional controllers for straddle-type vehicles, such as those disclosed in JP-A-2013-173426, fail to adequately stabilize the vehicle's posture, especially when the driver's intention is not considered during automatic posture control, leading to potential interference with the driver's operations.
Innovation Solution
A controller that acquires posture information during jumps and determines the driver's intention to control the vehicle, prohibiting automatic posture control when the driver intends to intervene, thereby allowing the driver to maintain control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If automatic posture control is executed when the straddle-type vehicle jumps, then the posture stabilization is improved, but the driver's operation may be interrupted when the driver has control intention
Solution Approach 1:
The system performs preliminary detection of driver intention (throttle operation, brake operation, clutch operation) before executing automatic posture control. By checking these operations in advance, the system determines whether to activate automatic control, thereby preventing interruption of driver operations while maintaining posture stabilization when needed
Solution Approach 2:
The system dynamically adjusts the activation state of automatic posture control based on real-time detection of driver operations. When driver operations are detected, automatic control is deactivated; when no driver operations are detected, automatic control is activated. This dynamic switching resolves the contradiction between maintaining posture stabilization and allowing driver operation

AI summary
The present invention obtains a controller and a control method capable of appropriately stabilizing a posture of a straddle-type vehicle.In the controller and the control method according to the present invention, when the straddle-type vehicle jumps, automatic posture control for controlling the posture of the straddle type vehicle by increasing or reducing a rotational frequency of a wheel is executed in accordance with posture information at the time when the straddle-type vehicle jumps. Furthermore, in the case where it is determined whether a driver has intention to control the posture of the straddle-type vehicle at the time when the straddle-type vehicle jumps without relying on the automatic posture control and where it is determined that the driver has the intention, the automatic posture control is prohibited.
